Dear MrEngman I found your tutorial earlier but this does not work with my Raspberry.
The real device is found @USB and drivers are downloaded well.

The adapter even can connect to a wifi but with iwconfig I can't start monitor mode because the driver is not detected properly.
When I for example use airmon-ng to check whats going on I see that driver is not running well.

The long name you see for your wifi is how Raspbian Stretch originally named network devices. It was changed in the new updates so why you still see it like that I'm not sure. I think there is an option in raspi-config that will enable you to get the name back to wlanx, etc.

Just for reference... Got the driver in install-wifi (version 4.3.14) to work with RTL8811AU chip wifi dongle. This is even on kernel 4.14.33(-v7+) no less. But any newer version of the driver source, say 4.3.20 for example, the RTL8812AU driver does not see the RTL8811AU chip. Not have I found any of the GitHub sources to work that newer than 4.3.14 from ether the RTL8812AU or RTL8811AU driver sets.

I install that driver on all my different Pi (Pi 0, P0W, B+, 2B, 3B, 3B+) with my script and I don't see any problems so I'm sure it is not an issue with the driver or my script.

When a driver is installed it needs to be registered and this is done using the depmod command. It updates a number of files as far as I know to create a list of available modules/drivers the kernel is able to use and it is possible one of the files it is trying to update may be corrupt.

One other thing is the value 'qpp_ddfl\ufffdte' it is showing. I don't know what this is but could it be a corrupt file? I don't know, but if it is is it this that is causing your issue. You could try searching for 'qpp_ddfl' or 'ufffdte' in the modules directory to see if they exist and deleting them if they do.

Then try running command sudo depmod -a again to see if it works.

Im trying to increase the speed of my AP and need to know the ht_capab and vht_capab flags enabled in the driver to put in hostapd.conf

And idea where i could find them? i have seen a post somewhere that the ht ones are listed with "iw list" but the vht ones he had to find in source code.

Thanks,

Hi Hootie81,

Sorry, but I don't think I can help. I compile several wifi drivers but knowing the internals of the drivers and how they work is a totally different matter. I tried command iw list and it outputs a load of data but whether that is useful I don't know.

Greetings All,
MrEngman, i noticed in this thread you mention the source you use for building your drivers in your installer, which BTW I love, use it for my trl8192EU all the time, however as the driver for the rtl8812 your building off doesn't support injection or changing the tx power via "iw wlanx set txpower fixed xxxx" i went on the hunt for a different source. This lead me to https://github.com/aircrack-ng/rtl8812au which supports all of the above along with turning the LED on/off and also seems to be using a newer rtl driver then the source your building from.

I've also experienced an issue with the driver installed by install-wifi dropping the connection to me Samsung S7 hotspot, (i use a PI as a NAT gateway with two wi-fi adapters) this seems to be more stable with the alternate driver source.

anyway as your the one doing all the work for these rtl88xx drivers its completely up-to you if you'd like to look at the alternate source.

either way keep up the good work.

Hi sealy_au,

Thanks for the post. I've got quite a list of 8812au sources from github and other places but not this one. As it's fairy new I shall definitely take a look and check it out myself.

MrEngman - I have noticed that you have upgraded 8812au drivers to v5.2.20.2_28373.20180619. And finally my TP-Link -T4UHv1 seems to be stable on ac 5GHz channels. I have been fighting with ac stability for quite long trying multiple github sources. The best results I had were with v5.2.20_25672.20171213 from TP-link website after small tweaking to make them working on RPi. But it was not perfect neither. Your version seems to work perfectly. Only what I am missing is /proc/net/8812au access. Could you let me know which github source you are using? So maybe I can tweak it to my liking.
